FRED WABTHER, OF DOVER, OHIO.

ROLL-POLISHER.

To all whom it may concern Be it known that I, FRED VVARTIIER, a citizenof the United States, and a resident of Dover, in the county ofTuscarawas and State of Ohio, have invented a new and 1111.-

proved Roll-Polisher, of which the following is a full, clear, and exactdescription.

My invention relates to a device for polishing the rolls of a rollingmill during the operation of the mill. An object of the invention is toprovide a simple and inexpensive device which can be easily attached toa rolling mill and with which the polishing of the rolls may be carriedon during the working of the mill.

Another object of the invention is to provide a polishing device forrolling mills in which the carrier of the polishing means is detachableso that the same can be removed when the device is not in use.

A still further object of the invention is to provide a polishing devicein which the polishing member is maintained yieldingly against thesurface to be polished.

\Vith the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of a'rolling mill provided with a polishingdevice embodying my invention;

Fig. 2 is a section on line 22, Fig. 3;

Fig.3 is a side elevation of the mill, the polishing device being shownin dotted line;

Fig. 4: is an enlarged section on line 14, Fig. 1; and

Fig. 5 is a similar section showing the polishing device in inoperativeposition.

Referring to the drawings, 7 is a polishing-stone carrier or supportwhich has a restricted opening 8 through which the reduced end 9 of thepolishing member 10 projects. The head 11 of the polishing member isaccommodated within the carrier and it prevents the yielding member 12within the carrier from forcing the polishing member out of the carrier.Preferably a plate 13 is interposed between the head 11 and the yieldingmembers 12. To facilitate the introduction and removal of the polishingSpecification of Letters Batent.

member, pin openings let are provided in the carrier so that pins may beinserted in front of the plate 13, thereby relieving the polishingmember 10 of pressure from the springs 12.

The carrier 7 has a yoke 15 open at the lower end so that the carriermay be hooked on to a bar 16 the ends of which are connected to movewith links 17 which are suspended from a frame 18 of the rolling mill.The bar 16 has preferably a shoulder 19 to engage the end of the yoke 15and increase the stability of the carrier on the bar. To facilitate thelongitudinal movement of the carrier on the bar, rolling members 20 areinterposed between the upper edge of the bar and the yoke.

Theswingingmovement of the bar and, therefore,'of the carrier thereon toand from the roller 21 of the mill is controlled by cams 22 which havetheir bearing on the frame 18 and which cams act against the links 17.The weight of the carrier and bar normally tends to move the polishingmember from the roll. The movement of the cams against the links forcesthe polishing member 10 into engagement with the roller 21 against theresistance of the springs 12.

The longitudinal movement of the carrier on the bar is controlled by ascrew 23 to which motion may be imparted from any suitablemotion-transmission means 21. Preferably a clutch 25 is provided betweenthe motion-transmission means and the screw so that the rotation of thescrew may be arrested at any desired time without interference with themotion-transmission means and to allow the polishing of any part of theroll. The carrier 7 is provided with a lug 26 having threads 27 whichmesh with the screw when the bar is moved by the cam to bring thepolishing member 10 into engagement with the roll. This engagement ofthe carrier with the screw causes the carrier to travel along the barand polishes the roll while the same rotates.

The thread of the screw stops short of one end so that when the carrierreaches the end of its travel it is disengaged from the screw. Thecarrier can then be directly removed from the bar, and for this purposean opening 28 is provided in the upper part of the yoke (see Fig. 1) tofacilitate the engagement of the tongues to raise the carrier of thebar. It is self-evident that when the cams are released from the linksthe carrier ished, a bar mounted to swing to and from the roll, apolishing-member carrier mounted to travel along the bar, and means forswinging the bar to and from the roll.

2. In combination with a roll to be polished, a bar mounted to swingto'and from the roll, a carrier mounted to travel along the bar, meansfor feeding the carrier along the bar adapted'to be disengaged from thecarrier when the bar is swung from the roll, and means for moving thebar toward the roll whereby the carrier is brought into engagement withthe feeding means.

3. In combination with a roll to be polished, a bar mounted toswing toand from the roll, a carrier mounted to travel along the bar, apolishing member yieldingly mounted in the carrier, means for moving thebarteward the roll whereby the polishing member is caused to engage theroll, and means for feeding the carrier along the bar adapted to beengaged by the carrier when the polishing member engages the roll.

4:. In combination with a roll to be polished, a bar mounted to swing toand from the roll, a carrier removably suspended mean"? I from thebar,"a polishing member yieldingly supported within the carrier toengage the roll, means forv feeding the carrier along the bar, and meansfor bringing the bar toward the roll whereby the polishing member isbrought into engagement with the roll and the carrier into engagementwith the feedmg means.

5. In combination with a rollto be polished, a bar, links for suspendingthe bar so that the same may be swung to and from the roll, cams forengaging the links whereby the bar may be moved toward the roll, acarrier suspended from the bar and mounted to move alongside of the bar,a polishing member yieldingly supported within the carrier, and a screw,said carrier having threads adapted to engage the screw when the bar ismoved by the cams toward the roll and bring the polishing member intoengagement with the roll.

6.' In combination -with a roll to be polished, a bar suspended to swingto and from the roll, eccentrics for moving the bar toward the'roll, acarrier removably suspended from the bar, a feed screw, and a polishingmember yieldingly supponted within the carrier, said carrier having athreaded portion adapted to engage the screw when the bar is moved bythe eccentric toward the roll to bring the polishing member intoengagement with the roll.
